Abstract

The invention discloses a machine tool. The machine tool comprises a base, a machine head, a working table and a rack. Wherein both the machine and the working table can move relative to the base, the rack is fixed on the machine head and connected with a first gear in a driving mode, a first spindle is fixedly connected with the first gear and a second gear connected with a third gear in a driving mode, the third gear is fixed at one end of a second spindle, the other end of the second spindle stretches into a screw hole arranged on the working table, the second spindle is provided with a thread matching with the screw hole, and a fixing board fixed relative to the base is sleeved on the second spindle to prevent the third gear from axially closing to the working table automatically. According to the machine tool, the machine head and the working table can operate synchronously with no machine to be added, and repeated machining is avoided.

Description

A kind of machining tool

Technical field

The present invention relates to a kind of machining tool.

Background technology

The process of gear is used milling machine, and the milling machine cutter is mainly used in the teeth groove that thins gear, and it is linear that the route that the cutter of milling machine is passed by is; The problem that prior art exists is: cutter is reciprocating according to projected route, and the contact point of cutter and teeth groove is less than normal, can not once accomplish; Otherwise; Not only because resistance is excessive possibly damage cutter, process also defectively, demand improvement urgently.

Summary of the invention

Problem to prior art exists the objective of the invention is to propose a kind of machining tool, and need not add any machinery can be so that head and workbench synchronous operation prevent to repeat processing.

For reaching this purpose, the present invention adopts following technical scheme:

A kind of machining tool comprises base, head, workbench, and head and workbench all can move with respect to base; Also comprise the tooth bar that is fixed on the head; Tooth bar first gear that is in transmission connection, first rotating shaft is fixedly connected first gear and second gear, and second gear drive connects the 3rd gear; Second rotating shaft, one end is fixed the 3rd gear; The other end stretches into the screw that is opened in workbench, and second rotating shaft is provided with the screw thread that cooperates with screw, with respect to fixed head socket second rotating shaft of fixed position base to stop the 3rd gear driving shaft near workbench.Tooth bar overlaps first gear near an end of workbench, the other end head that is rotationally connected.Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:

The present invention is in actual process, and when head machines, workbench is moved; When reprocessing, the Working position of cutter changes, and does not duplicate processing; The head moving belt moves movable workbench, and the frequency that both move is consistent, does not add machinery and can make the two synchronous.

The specific embodiment

Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment:

Embodiment 1

Propose a kind of machining tool, comprise base 1, head 2, workbench 3, head 2 all can be with respect to base 1 motion with workbench 3; Also comprise the tooth bar 4 that is fixed on the head 2; Tooth bar 4 first gear, 5, the first rotating shafts 11 that are in transmission connection are fixedly connected first gears 5 and second gear, 6, the second gears 6 the 3rd gear 7 that is in transmission connection; Second rotating shaft, 9 one ends are fixed the 3rd gear 3; The other end stretches into screw 10, the second rotating shafts 9 that are opened in workbench 3 and is provided with the screw thread that cooperates with screw 10, with respect to fixed head 8 sockets second rotating shaft 9 of base 1 fixed-site to stop the 3rd gear 7 driving shafts near workbench 3.Tooth bar 4 overlaps first gear 5 near an end of workbench 3, the other end head 2 that is rotationally connected.

When head 2 when workbench 3 directions are advanced, tooth bar 4 will drive first gear 5 and rotate, first gear 5 drives second gear 6; Second gear 6 drives the 3rd gear 3, the three gears 3 and rotates, and the second fixing with it rotating shaft 9 is rotated; Because second rotating shaft 9 is provided with the screw thread that cooperates with screw 10, and fixed head 8 stops the 3rd gear 7 driving shafts near workbench 3, makes that workbench 3 will be initiatively near the 3rd gear 7; After head 2 machined, workbench 3 moved, during head 2 reprocessing; The Working position of cutter changes, and can not duplicate processing, moves through the moving workbench 3 of the moving belt of head 2; Both travel frequencies are also consistent, do not add other machineries and can reach that the two is synchronous.

The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
